纱线与组织结构对机织物凉爽性能影响

Impact of yarns and weave structures on the coolness of woven fabrics

通过优选搭配不同功能的凉爽纤维,开发出一款夏季轻薄凉爽机织物。选择涤纶/薄荷纤维混纺纱作为经纱,选用不同锦纶纤维作为纬纱,选择平纹、斜纹、缎纹为织物组织,制备出了12种样品,探究不同纬纱和织物组织结构对面料热湿舒适性能的影响。结果表明,12种样品中缎纹织物热湿传递性能最好;平纹织物接触瞬间凉感较好;凉感锦纶确实增加了织物的凉爽性能,但是在结构较为紧密的组织中湿传递性能却较差;细旦锦纶的热湿传递性能与凉感锦纶相近,但透气性能较差;十字形截面锦纶在湿传递性能上较好,但是导热性较差。

A lightweight and cooling woven fabric for summer was developed by selecting and combining different cooling fibers.Twelve samples were produced by selecting polyester/mint blended yarn as warp yarn,nylon fiber as weft yarn and plain,and twill and satin as fabric weave to investigate the impact of different weft yarns and fabric structures on the thermal and moisture comfort properties of the fabrics.The results showed that twill and satin fabrics had better thermal and moisture transfer performance;plain weave fabrics provided a good cooling sensation upon contact;cool nylon indeed enhanced the cooling of the fabric,but it showed poor moisture transfer performance in tightly woven structures.Micro-denier nylon had similar thermal and moisture transfer performance to cool-feel nylon but had lower air permeability and cross-sectional nylon had better moisture transfer performance but lower thermal conductivity.
